Lifespan, longevity, and ageing

Maximum longevity: 18.2 years (captivity) Observations: Although it has been claimed that these animals live up to 22 years in captivity (Bernhard Grzimek 1990), this is unverified. The longevity record in captivity belongs to a female that was 18.2 years of age when she died (Richard Weigl 2005).
